The purpose of this study is to verify whether education on the placebo effect has significant impacts on the knowledge of the placebo effect, as well as the intention of healing food intake. For this purpose, 37 experimental group students and 29 control group students participated in the experiment. The results were as follows. First, education on the placebo effect did not appear to have significant impact on the functional value although it did have significant impact on emotional value and nutritional value. Second, knowledge of the placebo effect gained from the education had significant influence on intention of healing food intake. Third, only nutritional value showed a statistically positive (+) impact on intention of healing food intake.

It takes much of times and efforts for mathematical knowledge to be regarded as truth. Mathematical knowledge has been added, and modified, and even proved to be false. Mathematical knowledge consists of mathematical languages, statements, reasonings, questions, metamathematical views. These elements have been changed constantly by investigations and refutations of mathematicians, by modification of proofs considering the refutations, by introduction of new concepts, by additions of questions about new concepts, by efforts to get answers to new questions, by attempts to apply previous studies to the present, constantly. This study introduces the change of mathematical knowledge instituted by filcher, and presents examples of the change.

체육전공에서 해부학을 통해 스포츠 상해, 운동역학적 적용, 인체의 병리나 생리적인 지식을 습득할 수 있는 바탕이 된다. 그러므로 해부학적 기초가 없이 운동생리학, 생체역학, 측정평가, 운동처방 등 여러 응용학문에 대한 이해가 불가능하다. 대부분 체육전공에서 해부학을 전공필수로 지정하여 그 중요성을 강조하고 있다. 체육전공학과는 학과특성 및 교육시설 등 여러 가지 문제로 인해 해부학 실습교육이 어렵고, 특히 체육 특기생 경우 잦은 시합으로 수업의 결손이 많다. 또한 체육학과 전공교수는 학과특성상 대부분이 체육전공자로서 최근 의과대학에서 해부학을 포함한 기초의학전공 교수들의 감소되는 현상으로 건강-의료-보건관련 학과의 기초의학강의의 수요를 충족시키는데 어려움이 존재하여 학과 내 해부학강의도 체육전공교수들이 직접하고 있는 실정이다. 기초의학전공자가 아닌 교원의 해부학강의는 깊이 있는 해부학지식을 전달하는데 제한적이며 교수의 강의에 대한 부담도 존재한다. 따라서 본 연구는 2007년부터 2009년 동안 강원대학교 스포츠과학부 학생들을 대상으로 자체 제작한 가상강의 컨텐츠와 해부실습, 그리고 면대면 강의를 병행한 혼합강의를 실시한 후 설문조사를 통해 체육전공학생들의 효과적인 해부학지식전달의 방식으로 그 도입을 제시하고자 한다.

This research took an interpretive approach to investigate professional mathematicians' conception of mathematics, particularly focusing on their beliefs about the nature of mathematics as a discipline, and the relation between the discipline and themselves as knowers. The analysis shows that the professional mathematicians consider mathematics as human practice. For mathematicians, mathematics as a product is considered as a crystalization of practice that emerges in the dialogical relation between the discipline and its practitioners. This dialogical nature of mathematics suggests that professional mathematicians consider mathematics not as isolated fixed knowledge but as something they are playfully engaged with. The results of this research extend our understanding of what mathematics is and provide an alternative perspective on mathematics to make the learning of mathematics more accessible by dismantling the myth of the rationalist pure objectivity in mathematics.

The purpose of this paper was to investigate mathematics teachers' mathematical content knowledge about quadratic curves. Three components of mathematical knowledge are needed for teaching: (i) knowing school mathematics, (ii) knowing process of school mathematics, (iii) making connections between school mathematics and advanced mathematics. 24 mathematics teachers were asked to perform 10 questions based on mathematics curriculum. The results showed that mathematics teachers had some difficulties in conic section definitions and eccentricity definitions of ellipse and hyperbola. And they also got difficulty in Dandellin sphere proof of the equivalence of conic section definitions and quadratic curve definitions. Especially, no one answered correctly to the question about the definition of eccentricity. The ratio of correct answer for the question about constructing tangent lines of quadratic curves is less than that for the question about the applications of the properties of tangent lines. These findings suggests that it is needed that to provide plenty of opportunities to learn mathematical content knowledge in teacher education programs.

Beyond the simple stage of technical development, the growth of information networks have changed areas such as the economy, communities, and education. Existing knowledge and new knowledge about these things have developed and either coexist or conflict with each other. It is difficult to predict the result of this interaction since old and new information is changing so quickly. The transition from a simple communication to an interactive communication is related to a changed communication environment which involves a more complex level of understanding. Establishing the new design concept which is aimed at the future and developing new educational programs which respond to these new information networks are important in order to educate designers who can adjust to the new information network era and construct design education. This paper reports research about the process of developing new education systems that explore the new design paradigms, the changing information network, and the proper approaches to developing design education programs which fulfill these requirements.

Criticism has been raised that the way of teaching weights in the 3rd and 4th graders of elementary school is different between the 2015 revised math curriculum and the 2015 revised science curriculum, causing confusion among elementary school teachers and students. This study tried to confirm the social recognition that should be considered in the process of didactic transformation which means transformation from knowledge to used into knowledge to taught and to compare the variations of didactic transformations differently according to didactic intentions. The research analyzes and synthesizes the root of the meaning of weight, weight in the international standard system of units SI, weight implemented in Korean mathematics curriculum and textbooks, Singaporean mathematics curriculum and textbooks, USA mathematics curriculum and textbooks, and Korean science curriculum and textbooks. Through this analysis, a pedagogical perspective on how to define and teach weight in elementary school as knowledge to be taught was derived.

The purpose of this study was to explore changes in elementary teachers' modeling pPCK (personal PCK) resulting from knowledge exchange within the realms of PCK described in the Refined Consensus Model (hereafter RCM). For this purpose, a professional learning community (hereafter PLC) was established for three elementary school teachers to facilitate knowledge exchange specifically focused on science modeling instructions. The study then analyzed the CoRe (content representations) written by the research participants twice to explore any changes in modeling pPCK (personal PCK). In addition, the discourse shared by the participants in the PLC and the data from the in-depth interviews were also analyzed using grounded theory research methods. The results of the study showed that there was no significant change in knowledge of the science curriculum in elementary teachers' modeling pPCK, but there were changes in orientations toward teaching science, knowledge of students' understanding in science, knowledge of instructional strategies and representations, and knowledge of assessment of science learning. Furthermore, the analysis of PLC discourse and in-depth interviews showed that modeling instructions reflection (ePCK; enacted PCK) and educational research-based modeling cPCK (collective PCK) influenced these changes in teachers' modeling pPCK. Accordingly, this study suggests recommendations for pedagogical approaches aimed at improving teachers' modeling PCK.

The purpose of this study was to examine the types and characteristics of the knowledge constructed by pre-service secondary science teachers. Data included 26 student-teachers' narratives regarding their experiences in teaching high school students who were enrolled in extra-curricular science classes. It was revealed that the pre-service teachers awoke to the importance of subject matter knowledge, and learned it themselves in the situation of their own teaching. Especially their concern about science content knowledge was strongly associated with the matter of didactic transposition of the knowledge. The result also showed that the pre-service teachers constructed knowledge about the relationship with students as well as pedagogical knowledge to help students learn, and that they newly realized the nature of science in the context of teaching science. In addition, the teaching experiences allowed for the student-teachers to develop knowledge of oneself as a teacher and knowledge about science education in schools. It was believed that the knowledge constructed personally by the pre-service teachers from their teaching experiences could be a platform for the development of teacher expertise. Implications of the present study for science teacher education and relevant research were discussed.
